Any kid with a magnifying class can tell you what curved class can do with light. My point was that if building projects take in account which way the sun will move in the sky, then they should take into account what the sun might do when it hits the building.

You are very right and I dont see how they might have foreseen this. It is quite unusual for the windows on a building to start melting cars, especially in a mild climate like London. The fact remains that if it can mess a Jaguar up what happens when the sun rays are concentrated into a flat across the street that may have a small child or elderly person who may not be to leave the room when it starts getting hot.
